Bowser's Castle is a race course in Mario Kart 7 which seems to have the structure of a Haunted Mansion. It has cobwebs, lava pillars, Thwomps, and stairs. This track, as some previous others, is the third race in the Special Cup.

This track starts off on a separate platform with a ramp to glide into Bowser's Castle. There are two entrances, an upper level and a lower level if the upper level is missed while gliding. The two levels have a set of stairs with Thwomps and inclining slopes that lead into one room filled with lava pools and sharp turns. Past that room is a wide wooden rotating tunnel that ends by a lake filled with water, some pipes pouring lava, and lava-filled edges. Afterward, racers return to land on a mountain side passing by lava waterfalls as the racers drive up the mountain. At the end of the mountain is a sharp wide turn that ends with a ramp and drivers will glide to the finish line in the air and land on the entrance to continue the race.
